Diagnostic Testing & Assessment

Psychological, psychoeducational, and neuropsychological assessment

Brookside Psychologists offers psychological assessments to clarify mental health conditions, disability issues, and mental health diagnoses, such as depression, anxiety disorders, or chronic pain.

The practice also provides psychoeducational assessments for identification of learning disabilities and provision of recommendations regarding work and academic accommodations.

Our clinicians provide specialized neuropsychological assessment and treatment planning with a primary focus on recovery from traumatic brain injury (TBI) and concussion as well as identification of developmental issues (such as Autism-spectrum disorder) or neurodegenerative issues (such as Alzheimer’s or other dementias).

Medical-legal examinations are provided by psychologists with a range of clinical and research experience in the areas of traumatic brain injury, epilepsy, stroke, and learning disabilities.  Assessment following automobile accidents are provided, including Catastrophic Impairment assessments. Insurer Examinations are available, as well as psychovocational assessment.


Psychoeducational & diagnostic testing is available for kids and teens at our Burlington and St. Catharines offices. Assessments can help address behaviour issues, learning difficulties, attention problems, or emotional distress . Specialized assessment of developmental difficulties, Autism-spectrum disorders, and medical conditions (such as Epilepsy, cancer, or MS) is also available.


Psychological, psychoeducational, psychovocational, and neuropsychological testing & assessment are available for adults regarding learning disabilities, ADD/ADHD, persistent symptoms following concussion, traumatic brain injury, and mental health conditions such as anxiety and depression.


Diagnostic testing for dementia and mild cognitive impairment is available for seniors in Burlington, St. Catharines, and Owen Sound. Testing can help to identify any emotional or cognitive changes, such as declines in memory or thinking skills, depression, anxiety, or functional declines. A neuropsychologist can help determine whether these changes reflect a normal aging process or else a condition that will require treatment, such as depression, complex and persistent grief or anxiety, or a neurodegenerative disorder (like Alzheimer’s disease or Parkinson’s dementia for example).

mental health assessment

Psychological and mental health assessments are provided at all office locations to clarify mental health conditions, disability issues, and mental health diagnoses, such as depression, anxiety disorders, or chronic pain.

A psychological assessment typically involes a 1.5 to 2 hour interview with the client as well as possible follow up interview with someone who knows the client well. Testing involves administration of self-report questionnaires that ask about personality characteristics, symptoms (such as mood changes, memory issues, relational difficulties, and pain for example), and functioning. Following completion of the assessment, a report is prepared that contains information about the presenting problem(s), the results of the assessment, diagnoses, prognosis, and treatment recommendations. Clients are often invited to a 1-hour feedback session with the clinician to review the report, to talk about the conclusions, and to discuss any treatment planning.

Is your child…

  • not working up to their potential in school?
  • showing behavioral difficulties (i.e., impulsivity, distractibility, inattention) at home and/or school?
  • having trouble paying attention?
  • not feeling challenged enough?
  • bored in class?
  • having emotional difficulties (i.e., depression, anxiety, etc…)?

If you answered yes to any of these questions, a psychological assessment may be recommended.

At Brookside Psychologists, our licensed Psychologists provide diagnostic testing for individuals from four years of age through adulthood. An assessment can address the following issues:

Each child is different, and evaluations are tailored to the specific referral question.

neuropsychological assessment

The purpose of a neuropsychological assessment is to determine the presence and severity of any cognitive, emotional, and/or behavioural  difficulties associated with possible brain damage (from things like a traumatic brain injury or stroke), brain disease (like a brain tumor or Alzheimer’s dementia, for example), severe mental illness (like chronic severe depression or psychosis), or developmental condition (such as Autism-spectrum disorders, ADD/ADHD, learning difficulties).

Neuropsychological assessments involve testing of cognition (for example, memory, attention, language, problem solving), emotional functioning (through self-report questionnaires asking about mood, relationships, etc.), and behaviour.

Based on the results of testing, the neuropsychologist can diagnose the condition that is causing the difficulty, and also determine what kind of treatment is required. Neuropsychological assessment can also help determine a person’s level of mental and behavioural functioning pertaining to their ability to succeed in school or work, and whether they are disabled from working.

A neuropsychological assessment can involve 1 to 3 days of testing (with breaks of course!). During the first meeting, a clinical interview is conducted (about 1.5 to 2 hours). Then, the client is asked to complete some self-report questionnaires asking about symptoms, personality, and functioning. For the majority of the assessment, time is spent completing all sorts of cognitive tests. Most of these tests are done with an examiner sitting across the table from you (called a “psychometrist”). Some of the tests are done on the computer.

Because the assessment can be lengthy, some people prefer to break the assessment up across a few days. Others prefer to complete it in 1 or 1.5 days. Please let us know if there is anything you need to make your assessment more manageable or comfortable. We are happy to accommodate as best we can!


A Psychovocational Assessment is intended to “match” a person’s abilities (aptitudes, skills) with the specific reasoning and learning requirements of a job or training goal. It involves testing cognition (intelligence, memory, attention, organization skills, etc.), emotional and behavioural functioning, and work/academic interests.  This type of assessment is often requested for persons who are unable to return to work in their typical job or lifestyle activities due to the restrictions imposed by an injury. A vocational assessment can also help to identify vocational alternatives that are consistent with a person’s aptitudes, interests, skills, and physical abilities.

Comprehensive Catastrophic Impairment Assessments are provided in the context of the American Medical Association Guidelines 4th Edition & 6th Edition related to disability. The practice also provides submission of Applications for Determination of Catastrophic Impairment (OCF-19). 

Dr. Lesley Miller is a member of the Canadian Society of Medical Evaluators. She has completed numerous Catastrophic assessment reports and applications. She has completed training in pre- and post- June 1, 2016 Catastrophic Impairment Assessment, including completion of the following:

Dr. Miller is certified as a Catastrophic Impairment Examiner (Mental and Behavioural) by the Canadian Society of Medical Evaluators and the Canadian Academy of Psychologists in Disability Assessment (CAPDA).
psychological assessment

The practice offers Psychological and Neuropsychological Insurer Examinations.  An Insurer Examination (IE) may be conducted to determine the cause, extent and psychological treatment of a work-related or other injury where liability is at issue; whether an individual has reached maximum benefit from treatment; and whether any permanent impairment remains after treatment. An Insurance Examination may be conducted at the behest of an employer or an insurance carrier to obtain an independent opinion of the clinical status of the individual.  Auto insurance carriers have a legal right to this request.

medical legal examination

Medical-Legal Psychological and Neuropsychological Assessments are provided for use as evidence in litigation; for example in relation to compensation for work-related stress or after a traumatic event such as an accident. The Psychological Assessment may be requested in order to establish a link between the trauma and the victim’s psychological condition, or to determine the extent of psychological harm. Medical-Legal Assessments address issues such as:

  • Reasonableness of treatment and rehabilitation
  • Determination of catastrophic impairment (C-CAT  MB Certified)
  • Tort issues such as permanent and serious impairment
  • Ability to work
  • Loss of economic advantage, pain and suffering, or loss of quality of life
